IMPROVEMENT IN EYE-GLASSES.

The Schedule referred to in these Letten Patent and making-part of thesame.

To all whom 'it may conce/rn Be it known` that I, RICHARD STRAUBEII, ofW-illiamsburg, in the county of Kings, and State of 'New York, haveinvented a newl and useful Improvement in Eye-Glasses; and I do-herebydeclare that the following is a full, clear, and exact description'thereof', which will enable others skilled in the art tomake and use thesame, reference being had. to the accompanying drawing, forming part ofthis specification, in y which- Figure 1 represents a front view of myimproved eye-glass, showing it expanded.

Figure 2 is a face view of the same, showing itfolded together.

Figure 3 is a sectional view of .the same on an enlarged scale. 1 Y

Similarletters of reference indicate corresponding parts. The object ofthis invention is tof A'so construct 'the frame of a pair of eye-glassesthat the glasses, when applied, will be in a horizontal line, asl theyare in spectacles, and that when'the instrument is folded together, theends of the U-spring will not project to be caught in the pockets o rotherwise.

The invention consists chiefly in arranging small coiled springs aroundthe pivots, by which the glass .frames are connected with the U-spring,so that thereby the glasses are held in the proper level, while they areallowed tobe'held against the ends of the U-spring,

to protect the same when folded together. 5. In the ordinaryeye-glassesnow in use, the glasses, are suspended in an inclined position from thesustain;

ingsp1ings,andare not straight, as in spectacles, their position beingthus less convenient and proper than it is in the latter instrument,which diiculty is entirely overcome by my invention.

A A, in the drawing, are`the two glass frames, of oval' or othersuitable shape. l

B is the central U-shaped spring, carrying the nose- 'pieces B', bywhich the instrument is secured-to the nose.

From the frames ,A projectv ears aa,which fit be tween ears b b, thatprojectfrom the-two sides of the spring B. v f

Pins c c, which are with their .ends securely fastened in the ears b bybeing squared or'otherwise, iit through enlarged apertures ot' the earsa.

- In the aperture oil each ear a is arranged a small coiled spring, d,which is, as in iig. 3, with its inner end secured to the pin c, whileits-outer end is secured to the ear a, as shown. y A

These springs d form, therefore, together with the Vpinsfc and ears a b,the connections between-@he frames A and holder B, and have thetendency. to

throwthe frames A up, until shoulders c on their eays a'strike shouldersf, or other stops on the spring as in lig. 3. The glasses 'are-therebyheld in line when applied as'indicated by the redvline g g in fig. 1.

. When the instrument is, however, folded together,

as in fig. 2, so that a hook or catch, h, on vone'frarne 'A, ts over andis held bya pin, i, of the other frame lugs 'a E, enclosing 'the springd,'as herein described,

for the. purpose specified'.
